DDOS attacks mainly occur in the network layer. Its most obvious characteristic is to send a large number of attack packets, consume network bandwidth resources and affect normal users' access. At present, the detection and defense technology for DDOS attacks in the network layer is quite mature, and at the same time, some new attack methods-DDOS attacks in the application layer have emerged. Different from network layer DDOS attacks, application layer DDOS attacks mostly imitate the access behavior of legitimate users and will not generate a large number of attack data packets during data transmission, but they will consume server resources through a large number of database queries and other operations, which is more difficult to detect. According to the different attack modes, DDOS attacks include reflection amplification attacks in addition to ordinary flooding attacks. This type of attack often uses a legitimate server as a reflector, which sends a large number of data packets to the target, thus causing greater harm. At present, DDOS attacks against DNS servers are also common. Attackers often send fake domain names to DNS servers, consuming DNS server resources. At the same time, due to the recursive query mechanism in DNS servers, DDOS attacks against DNS servers have a large impact range.否则项羽即便是有心以大局为重，也不好轻易拉下脸来。该剧将讲述从未想要当个乖女儿、好儿媳、好太太却不得不背负着一切的国家选手级超级女人林致雨以及对自己而言家人就是奢侈的崔镇宥一路寻找爱与家庭的奋斗故事。古装犯罪动作爽片《目中无人》由魏君子担任制片人，张哲监制，杨秉佳导演兼编剧，秦鹏飞担任动作导演，谢苗领衔主演，高维蔓、向皓、刘奔、张荻主演。身怀绝技的盲眼“捉刀人”成瞎子，遇上惨遭灭门和凌辱的酒家女倪燕，原本不想插手的他逐渐被卷入一场势力庞大的暗黑纷争中，成瞎子开始踏上了寻求公道的复仇之路，他的真实身份也随之揭晓。你想，那人就算再馋，也不敢冒这大风险进洞烧乌龟吃。为了不让自己的谎言曝光，绘里香只能去请求佐田，希望他能够假扮她的男友，让绘里香没有想到的是，表面上严肃正经的佐田，实际上是一个腹黑的“抖S”，而巧合的是，绘里香的内心里亦埋藏着“抖M”的特质，一对表里不一的男女一拍即合，上演了一出出荒诞但又充满了甜蜜的爱情喜剧。This picture looks weird.
